amount: add from_sat_i32 and from_sat_u32 methods for small constants
We have a ton of calls to `from_sat_unchecked` for small constants which were clearly in range, e.g. in fee.rs. Add a new constfn for these cases. Don't bother making a generic Into<u32>/Into<u16> variant because there isn't an obvious name for it. There are 7 instances where we're using this method with values that are out of range, which we leave as from_sat_unchecked for now.
